From the Web to the Cloud
• Computing history – pre 1993
• Web 1.0 - 1993 world-wide-web
• Web 2.0 - 2001 - user-created content
• Web 3.0 – 2009 – utility/cloud computing?
• Cloud Computing – What’s under the hood?
– Where are we now?
– Where are we going?
• Questions
Pre 1993 Computing
• Mainframes 1960s – IBM, CDC, HP, DEC, Amdahl
• Mini-Computers 1970s – DEC, Xerox
– ARPANET, UNIX, email
• Personal Computer 1980s – IBM, Compaq, Apple
– spreadsheets, graphics, word processors, hypertext, C++, computer games, TCP/IP
– 1982 Time’s “Man of the Year”

First IBM PC The main features that the IBM PC initially gave were as follows: •One or two 360k 5.25" floppy drives (early models had 120k byte single sided drives). •BASIC in ROM with cassette tape support. •Option of CP/M-86 or IBM PC-DOS. •Wide range of off-the-shelf software eg VisiCalc, Wordstar, SuperCalc, dBase II, which were easily ported from 8-bit CP/M. •Open platform for new software developments, from 8086 Assembler to a wide range of programming languages (eg PL/M, C, Basic). •Choice of either a high-quality monochrome text display or colour display capable of 2-colour medium resolution or 4-colour low resolution graphics. •Published hardware bus and layout design, allowing 3rd party add-ons. •Options of serial and parallel printer ports. •IBM on the front, hence world-class sales and marketing support.
Web 1.0 • 1984 – GNU project to develop and promote Open Source
Software launched by Richard Stallman
• 1990 – HTTP protocol and first WorldWideWeb interface designed and released by Tim Berners-Lee, CERN
• 1991 – Linux released by Linus Torvalds
• 1993 – First browser – Mosaic – Marc Anderson NCSA, later became first commercial browser – NetScape – then open-sourced as Mozilla (now Firefox)
• Search engines – 1990 – Archie; 1993 – Excite; 1994 – Lycos, AltaVista, Webcrawler; 1996 – Intomi; 1997 – Ask Jeeves (now ask.com); 1998 – Google launched; 2004 – Google went public
Web 2.0 - User Created Content
• 2001 – Wikipedia
• 2002 – Friendster
• 2003 – MySpace
• 2004 – Facebook
• 2005 – YouTube
• 2006 – Blogger fully supported by Google (blogging started in 1980s-1990s)
• 2006 – Twitter started
Web 3.0 – cloud computing?
What is Cloud Computing? CLOUD: Common, Location-independent, Online Utility provisioned on-Demand
• Common, in that it multiplexes demand from multiple customers and applications into a shared, common pool of computing resources.
• Location-independent, because data accessibility should follow you no matter where you are.
• Online, in the sense that it is accessible over an agile, geographically dispersed network, that is available anytime.
• A Utility because it provides value and offers usage-sensitive, pay-per-use pricing.
• on-Demand in that the ability to provision capacity or service should be as fast as possible to meet variable demand requirements, enhancing business agility
and providing capacity and scalability at the lowest total cost.

What’s under the hood?
• Layers – SaaS – Software as a Service
– PaaS – Platform as a Service
– IaaS – Infrastructure as a Service
• Virtualization
• Enterprise and/or open or hybrid
• Distributed connected data centres
• Green IT
Where are we now? • Many SaaS applications, some PaaS
• Amazon, Rackspace, VrSTORM IaaS
• Apps.gov – launched Sept 15, 2009
• Websphere (IBM), Sharepoint (Microsoft), VMware, Citrix – big corporate support for common portals and clouds
• VrSTORM – first open Canadian cloud solution provider
• Alberta cloud-based companies: Replicon, MoboVivo, Clinitrust, Kanata Health Solutions, Calgary Scientific, Cambrian House
• High on hype cycle
• Lots of creative destruction
Where are we going?
• Most businesses and applications only need very lightweight end-point devices
• Almost all applications will be deployed to the cloud
• Consider moving your applications to the cloud
• Decreased capital costs and operations
• Cloud utilities will provide competitive packages based on pay-per-use
